Micronesia double glass photovoltaic modules

Double-glass PV modules are emerging as a technology which can deliver excellent performance and excellent durability at a competitive cost. In this paper a glass–glass module technology that uses liquid silicone encapsulation is described. The combination of the glass–glass structure and silicone is shown to lead to exceptional durability.

Preface To further extend the s rvice life of photovoltaic modules, double glass photovoltaic module has cently been develop d and st died in the PV community. Double lass module contains two sheets of glass, whereby the back sheet is made of heat strengthened (semi-tempered) glass to substitute the traditional polymer backsheet.

Canadian Solar's Dymond double glass module passed 3 times IEC standard test and IEC 61730-2:2016 multiple combination of limit test and obtained VDE report, which fully indicate high lifetime and high reliability of this double glass module. This paper presents a detailed reliability study of Canadian Solar's Dymond double glass module.

Recently several double-glass (also called glass–glass or dual-glass modules) c-Si PV modules have been launched on the market, many of them by major PV manufacturers. These modules use a sheet of tempered glass at the rear of the module instead of the conventional polymer-based backsheet. There are several reasons why this structure is appealing.

Double-glass modules boast increased reliability, especially for utility scale PV projects. These include better resistance to higher temperatures, humidity and UV conditions and have better mechanical stability, reducing the risk of microcracks during installation and operation.

Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun. According to the literature, double glass also has some potential risks besides the abovementioned advantages.
